Technical Field
[0001] The utility model relates to the technical field of molds, in particular to a socket die-cutting mold for a plastic guide rail of a film cutter. Background Art
[0002] When die-cutting a workpiece, the workpiece is die-cut by a die-cutting knife provided on an upper die holder. During the cutting process, the workpiece may be subjected to pressure and may be offset, deformed, and other problems, resulting in a change in the die-cutting position, which affects the processing accuracy of the workpiece.
[0003] To this end, the Chinese patent with authorization announcement number CN221912341U discloses a die-cutting mold, wherein a through hole is provided on the main body of the die, which passes through the upper and lower parts of the die body, and a hanging part is provided in the through hole. A pressing component is provided in the through hole and can be hung with the hanging part. The thickness of the pressing component is less than the thickness of the die body. When the die assembly is placed on the material, the pressing component presses on the material, and the pressing component is separated from the hanging part; when the die assembly is lifted, the pressing component can be hung on the hanging part, so that the pressing component can press on the material, preventing the material from being deformed during the die-cutting process, avoiding wrinkles, product abnormalities, inaccurate dimensions and other undesirable phenomena in the die-cut products, and improving the quality of the products; and when the upper mold plate presses the die assembly downward from the top of the die assembly, it drives the die-cutting blade downward to die-cut, avoiding interference of the pressing component with the upper mold plate when pressing the die assembly downward to die-cut the material.
[0004] However, while clamping the workpiece tightly can prevent it from shifting, it only works for workpieces with regular shapes. For workpieces with three-dimensional structures like plastic guide rails, directly clamping them can damage the original structure, causing deformation and breakage. Utility Model Content

[0026] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.
[0027] Reference Figure 1-Figure 5 : A socket die-cutting mold for the plastic guide rail of a film cutter, comprising a frame 1, on which an upper die base 11 and a lower die base 12 are provided; the upper die base 11 is provided with a first support 111 and a guide column 112, the first support 111 is provided with a die-cutting knife 1111, and the guide column 112 slides with the frame 1; the lower die base 12 is provided with a support assembly 2 for supporting the plastic guide rail 4, the support assembly 2 includes a mounting base 21 mounted on the lower die base 12, the mounting base 21 is provided with a guide bar 211 for guiding the movement of the plastic guide rail 4, and the guide bar 211 is located on the side of the mounting base 21 close to the lower die base 12.
[0028] The present invention realizes the function of accurately cutting the plastic guide rail 4 through the upper die base 11, the lower die base 12 and the mounting base 21, and the position of the plastic guide rail 4 can be stabilized by the guide bar 211 on the mounting base 21, avoiding the plastic guide rail 4 from being offset during the cutting process, solving the problem that the traditional die-cutting mold will cause the workpiece to deform when fixing the workpiece. The upper die base 11 is raised and lowered by the drive of a hydraulic rod, which is not shown in the figure. The plastic guide rail 4 is an elongated strip as a whole and has multiple cutting positions. For this reason, a guide bar 211 is provided on the mounting base 21 to support the plastic guide rail 4. The cooperation between the guide bar 211 and the plastic guide rail 4 can provide stable support for the plastic guide rail 4 during the die-cutting process, avoiding the problem of the plastic guide rail 4 being offset or deformed due to pressure during the cutting process, and can also guide the movement of the plastic guide rail 4 during loading and unloading, thereby improving the portability and stability of loading and unloading.
[0029] Reference Figure 3-Figure 5 : The support assembly 2 includes an upper support block 22 and a lower support block 23; the upper support block 22 is disposed on the mounting seat 21; the lower support block 23 is disposed on the mold; and the guide bar 211 is located between the upper support block 22 and the lower support block 23.
[0030] The present invention supports the plastic guide rail 4 from both the top and bottom via the upper support block 22 and the lower support block 23. Both the upper support block 22 and the lower support block 23 have raised portions for mating with the plastic guide rail 4. The shapes of the raised portions match the contact surface of the plastic guide rail 4, further enhancing the support stability of the plastic guide rail 4. Furthermore, during the die-cutting process, the upper support block 22 and the lower support block 23 support the plastic guide rail 4 from above and below, respectively. Even if the plastic guide rail 4 undergoes local deformation due to pressure during the cutting process, the lower support block 23 and the guide bar 211 stabilize the overall position of the plastic guide rail 4, preventing deviation in the cutting position.
[0031] Reference Figure 4 、 Figure 6 and Figure 7 : A support plate 3 for buffering impact during the die-cutting process is provided on the frame 1, and a main rod 31 and an elastic member 32 are provided under the support plate 3; the main rod 31 is installed on the frame 1, and a retractable auxiliary rod 311 is provided on the main rod 31. The end of the main rod 31 away from the auxiliary rod 311 is provided with a mounting block connected to the frame 1, and the end of the auxiliary rod 311 away from the main rod 31 is provided with a push block connected to the support plate 3; the two ends of the elastic member 32 are respectively connected to the frame 1 and the auxiliary rod 311.
[0032] The utility model realizes the function of buffering the impact during the die-cutting process through the support plate 3, the main rod 31, the auxiliary rod 311 and the elastic member 32. A hydraulic damper is provided in the main rod 31, which is not shown in the figure. In the working state, the upper die base 11 is driven downward by the hydraulic rod, and the upper die base 11 drives the die-cutting knife 1111 to move downward for die-cutting. In this process, when the upper die base 11 contacts the support plate 3 and pushes the support plate 3 downward, the elastic member 32 contracts after being compressed. The deformation of the elastic member 32 absorbs vibrations, avoids severe impact on the lower die base 12, and extends the service life of the mold. After the die-cutting work is completed, the auxiliary rod 311 is extended again under the elastic force of the elastic member 32, and the support plate 3 is driven upward and reset by the auxiliary rod 311. The damper provided in the main rod 31 can suppress the reciprocating vibration of the auxiliary rod 311 and the support plate 3, and quickly restore to a stable state.
[0033] Reference Figure 4 、 Figure 6 and Figure 7 : A limit plate 33 is provided on the frame 1 for limiting the downward movement distance of the support plate 3; a contact sensor 331 is provided on the limit plate 33.
[0034] The present invention realizes the function of automatically controlling the reset of the upper die holder 11 through the limit plate 33 and the contact sensor 331, thus avoiding the situation of over-cutting. A controller for human-machine interaction is provided on the frame 1. The contact sensor 331 and the hydraulic rod are electrically connected to the controller. The controller connects the contact sensor 331 and the hydraulic rod through a line. Its core function is: when the support plate 3 moves down and touches the limit plate 33, it receives the trigger signal sent by the contact sensor 331 in real time, and immediately sends an upward command to the hydraulic rod to retract it, driving the upper die holder 11 and the die-cutting knife 1111 to reset; at the same time, the controller integrates a human-machine interaction interface for equipment start-stop operation and working status monitoring. The controller is not shown in the figure. In the working state, the upper die holder 11 is driven downward by the hydraulic rod, and the upper die holder 11 drives the die-cutting knife 1111 downward to perform die-cutting. In this process, when the upper die holder 11 contacts the support plate 3, it pushes the support plate 3 downward, and the elastic member 32 is compressed and contracted. When the support plate 3 contacts the limit plate 33, the contact sensor 331 feeds back a signal to the controller, and the controller sends a signal to the hydraulic rod. The hydraulic rod controls the upper die holder 11 to move upward, controls the upper die holder 11 and the die cutter 1111 to reset, and completes a die cutting cycle.
[0035] Reference Figure 6 and Figure 7 : The limit plate 33 is provided with a guide rod 332 and a screw 333; the guide rod 332 slides with the frame 1; a threaded sleeve 334 is rotatably provided on the frame 1, and the threaded sleeve 334 is threadedly connected to the screw 333; the frame 1 is provided with a rotating handle 34 for driving the threaded sleeve 334 to rotate.
[0036] The present invention realizes the function of adjusting the height of the limit plate 33 through the guide rod 332 and the screw rod 333. Different die-cutting depths need to be set for different models of plastic guide rails 4. To this end, it is only necessary to adjust the height of the limit plate 33, and then control the hydraulic rod to drive the upper die base 11 to reset through the contact sensor 331 on the limit plate 33. The guide rod 332 and the screw rod 333 are both fixedly connected to the limit plate 33. When adjusting the height of the limit plate 33, the operator turns the rotary handle 34, and drives the threaded sleeve 334 to rotate by rotating the rotary handle 34. The threaded sleeve 334 drives the screw rod 333 threadedly connected thereto to rise and fall, and the screw rod 333 drives the limit plate 33 to rise and fall, thereby adjusting the height of the limit plate 33.
[0037] Reference Figure 6 and Figure 7 : A transmission shaft 341 is rotatably provided on the frame 1, and the rotating handle 34 is sleeved on the transmission shaft 341; the transmission shaft 341 and the threaded sleeve 334 are respectively sleeved with a first bevel gear 342 and a second bevel gear 343, and the first bevel gear 342 and the second bevel gear 343 are meshedly connected.
[0038] The utility model realizes the function of driving the threaded sleeve 334 to rotate by rotating the handle 34 through the transmission shaft 341, the first bevel gear 342 and the second bevel gear 343. When adjusting the height of the limit plate 33, the operator rotates the handle 34, which drives the transmission shaft 341 to rotate, and the transmission shaft 341 drives the first bevel gear 342 to rotate. The second bevel gear 343 drives the threaded sleeve 334 to rotate, and the threaded sleeve 334 drives the screw 333 to rise and fall, thereby adjusting the height of the limit plate 33.
[0039] Reference Figure 1 and Figure 2 : A guide plate 1112 is provided on the first support 111 and is slidably engaged with the frame 1.
[0040] The present invention achieves the function of guiding the first support 111 in ascending and descending directions through the guide plate 1112. The guide plate 1112 and the frame 1 slide together to guide the first support 111 in ascending and descending directions, thereby stabilizing the movement trajectory of the die-cutting blade 1111. During the die-cutting process, the cutting angle of the die-cutting blade 1111 is stabilized, thereby improving the die-cutting quality.
[0041] Reference Figure 1 : A blanking cabin 13 is provided on the frame 1, and the blanking cabin 13 is located directly below the lower die base 12. A blanking port connected to the blanking cabin 13 is provided below the lower die base 12.
[0042] The present invention achieves waste collection through a blanking chamber 13. A discharge port is located below the blanking chamber 13. During the die-cutting process, the die-cutting blade 1111 cuts the plastic guide rail 4, and the cut waste falls through the discharge port into the blanking chamber 13 under the action of gravity. The operator places a container below the blanking chamber 13 to collect the cut waste, preventing it from remaining in the die and affecting die-cutting quality.
[0043] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
